Education: The cheapest smartphones already sell at 10$ in Africa and Asia. By 2020, 70% of all humans will own a smartphone. That means everyone will have much the same access to world class education. Every child can use Khan Academy for everything he needs to learn at schools in First World countries. Further afield, the software has been launched in Indonesia and will be released it in Arabic, Swahili and Chinese this summer. The English app will be offered free, so that children in Africa can become fluent in English within half a year.
